Scuba divers have a vested interested in protecting the
coral reefs and ocean habitats they explore. After all, seeing cool fish and colourful
coral is the main reason divers descend below the surface.
The Australia-based Global Coral Reef Monitoring
Network estimated in
its latest report that 19% of the world’s original coral reef has already been
lost, another 15% will be “seriously threatened” in the next two decades and 20%
will be threatened with loss in the next 20 to 40 years. The good news is that
46% of reefs across the globe are considered “stable or
recovering rapidly”, and that’s up from a 30% estimate in 2004. The concern has
led to plenty
of efforts to save the reefs.
Here are a few ways you can give back to the sea while
still witnessing all it has to offer.
The Key Largo-based Reef
Environmental Education Foundation (REEF) teaches divers to be “citizen scientists” with
week-long field surveys that combine plenty of diving with a little classroom
work. Divers become expert fish spotters, helping compile a database of species
for the foundation, which is then used for scientific papers and research.
Trips, which normally start at about $1,000 for a week plus flights, are
offered in the Caribbean as well as in Canadian cold waters and the South
Pacific. Don’t want to commit to a whole trip? Divers and snorkelers can become
members of REEF (for free) and enter their own fish survey observations online.
hunts, an opportunity to capture and study the
invasive lionfish, a species that has been multiplying madly throughout the Atlantic,
specifically in the Caribbean and up the eastern coast of the United States.
Scientists believe a few were released in Florida when a home aquarium broke
during 1992’s Hurricane Andrew. With no natural predators in these waters, the red-and-white striped Pacific
Ocean-native has been gobbling up reef fish and putting other populations at
risk. Besides week-long REEF trips to the Bahamas among other destinations, dive
shops from North Carolina to the Cayman Islands to Honduras offer lionfish dives or “derbies”, in which the
problematic predator is rounded up and then cooked for dinner.
DiVo, an Australian
nonprofit group, organises and promotes volunteer research and conservation
opportunities both in Australia and around the world. A project in Bali has
divers and snorkelers spending a week transplanting and monitoring coral that
has been decimated by cyanide fishing, with volunteers living and working with
local fisherman. Closer to home, volunteer scuba enthusiasts in Sydney work
alongside university scientists to replant crayweed, a sea plant that serves as
habitat for abalone, lobsters and other fish. And the group offers reef survey
opportunities at Australia’s biggest dive attraction, the Great Barrier Reef.
The Florida Keys’ Coral
Restoration Foundation (CRF) is
the result of founder Ken Nedimyer’s passion for bringing coral -- and the
Keys’ ecosystem -- back to its former glory. Nedimyer developed a method of
growing elkhorn and staghorn coral in underwater nurseries and transplanting it
to the wild. His efforts have been so successful that this year CNN featured
efforts. Dive clubs can organise
up one- to three-day volunteer programs with CRF, which includes classroom
instruction on the reefs’ decline and restoration methods. Then, divers enter the
water, working in the nursery or transplanting the growing coral. Individual
divers can check the website for opportunities to join existing trips.
Hawaii’s Kaanapali Makai Watch uses volunteers to monitor herbivore fish in Maui’s protected
Kahekili Herbivore Fisheries Management Area. Divers are trained by the
project’s staff before being put to work gathering data. A volunteer might
watch an algae-eating fish – a parrotfish, for instance -- to see how many
bites it takes in a minute. The watch project is run by Hawaii’s Division of
Aquatic Resources, the non-profit Coral Reef Alliance (CORAL) and Project SEA-Link,
which promotes marine science and education. CORAL
also encourages Hawaii divers to be
“citizen scientists” and enter their reef monitoring observations online. Liz
Foote, CORAL’s Hawaii field manager, said that volunteers contribute excellent
data, but the program also “inspires stewardship,” so that volunteers get
involved in other conservation efforts on the islands.
Divers who want to clean up our waterways can
sign up with the global Project Aware Foundation, which promotes rubbish monitoring and clean-up
events around the world as part of its “Dive Against Debris” project. Divers
can launch their own event or join an established one in locations as diverse
as Thailand, Australia and Poland. Travelling to an exotic locale soon? Check
the Project Aware site
to see if you can volunteer dive time with a local event.
